A team of researchers from Manchester University claims to have identified the dominant process causing light-induced degradation in silicon solar cells. The process, termed “trap-assisted auger recombination”, arises from a defect in the bulk of the silicon material which lies dormant until exposed to sunlight.
U.S.-based PV Evolution Labs (PVEL) has found that Vikram Solar’s Somera monocrystalline silicon and Eldora polycrystalline silicon PV modules met and exceeded international quality and performance benchmarks.
While Bureau of India Standards certification is a genuine attempt by the Indian government to mitigate the risks associated with poor solar module quality, there are several reasons why it is not 100% effective. pv magazine India’s Uma Gupta investigates India’s efforts to ensure quality in its booming PV industry.
Founded in 2016, Prescinto Technologies is an industrial internet of things solution provider to the solar sector. After two years, Prescinto has found a footing in 13 countries across 4 GW of solar plant capacity. Backed by Gensol Group’s engineering experience across 20 GWs of renewable projects, Prescinto is able to transform that knowledge into code and empowers plants ‘onboarded’ on its platform.
As in many fast-growing solar marketplaces, some of the stories about PV quality to emerge from India have been the stuff of nightmares. But the industry is mobilizing in the form of a quality taskforce, writes Pranav R. Mehta, chairman of the National Solar Energy Federation of India.
India’s Ministry of New & Renewable Energy (MNRE) has issued guidelines for solar PV inverter manufacturers to get their products tested and approved by Bureau of India Standards (BIS) certified labs. These guidelines apply to off-grid, grid-tie and hybrid inverters of capacities up to 150 KW.
Rules on the composition of product containers, production line sample sizes for testing and technical information will come into force for manufacturers and distributors operating across the nation.
While Bureau of India Standards (BIS) certification is an honest attempt by the Indian government to mitigate risks associated with poor quality of modules, there are several reasons why this particular objective is currently not being met. pv magazine India’s Uma Gupta investigates India’s efforts to ensure quality in its booming PV industry.
National Institute of Solar Energy (NISE) will carry out inspections, verifications and quality checks on behalf of the Ministry of New and Renewable Energy (MNRE).
